0 CHROMATOGRAPHY OF ALKALOIDS, PART A, Volume 23A: THIN-LAYER CHROMATOGRAPHY

Description

The first of two books which provide an unparalleled reference source and handbook for everyone involved with alkaloid analyses. The first volume gives a comprehensive summary of the literature on thin layer chromatography of alkaloids. It presents the most effective methods for the separation and detection of alkaloids occurring in plant material, biological material, pharmaceutical preparations and drugs of abuse.

0 Alkaloids Chemical And Biological Perspectives Volume 12

About the Book

Acronycine, a potent antitumor agent, was discovered in the bark of the small Australian Rutaceous tree, "Acronychia baueri "Schott. This new work presents a comprehensive survey of the isolation, structure determination, methods of synthesis, and the biological properties of acronycine, as well as an account of natural and synthetic analogues of acronycine, and their biological properties.

Solanum alkaloids were reviewed in 1990 and this book surveys the new developments (isolation procedures, structural elucidation methods) and critically updates earlier reviews.

In addition it presents the interesting chemistry and synthesis of cyclopeptide alkaloids. These cyclopeptide alkaloids have been isolated from ascidians, sea hares, and cyanobacteria.
Also included are reviews of the use of the functionalized lactam, pyroglutamic acid, as a chiral template for the synthesis of alkaloids.

The second review examines the on-line coupling of capillary electrophoresis (CE) and mass spectrometry (MS) for the analysis of alkaloid mixtures.

Finally a review of oxygenated analogs of the alkaloid Marcfortine for their potent antiparasitic activity is included at the end of this work.

Each chapter in this volume has been reviewed by at least one expert in the field. Indexes for both subjects and organisms are provided.

0 Alkaloids: Chemical and Biological Perspectives, Volume 10

Book Description

Volume 10 of this series presents four timely reviews. Chapter 1 provides a fascinating account of the history of alkaloid discovery in Australia beginning with the isolation of the first alkaloid from an Australian plant, the Tasmanian sassafras (Atherosperma moschatum), by Zeyer in 1861. Also included is a comprehensive survey of alkaloid-bearing plants, and a section dealing with detection, estimation, extraction, and work-up procedures for alkaloids.

Chapter 2 provides a comprehensive update to the chapter on "Pyridine and Piperidine Alkaloids" which appeared in volume 3 of this series. The focus of this chapter is on new alkaloids isolated, biosynthesis, and biological properties.

Chapter 3 looks at "3-Alkylpiperidine Alkaloids Isolated from Marine Sponges in the Order Haplosclerida". Studies over the past thirty years have shown that sponges are a rich source of alkaloids. Many of these sponge alkaloids are related to each other by the presence of a 3-alkylpiperidine moiety in their structures and it happens that the sponges that have been reported to contain 3-alkylpiperidine alkaloids are all in the order Haplosclerida.

0 Alkaloids: Chemical and Biological Perspectives, Volume 11

Description

 

Volume 11 of this series presents five timely reviews on current research on alkaloids. Chapter 1 by Paul L. Schiff, Jr. is a monumental survey of research that has been carried out over the past decade on the Thalictrum alkaloids. Forty-six new alkaloids are described from fifteen species of the genus Thalictrum, as well as 116 alkaloids of known structure from thirty-six species and subspecies of the genus. The chapter includes discussions of isolation and structure elucidation, analysis, biosynthesis, cell culture, and pharmacology. Also featured are inclusive compilations of botanical sources, alkaloids by alkaloid types, and calculated molecular weights of the Thalictrum alkaloids.

Chapter 2 by Giovanni Appendino provides a fascinating treatment of Taxine, a collective name referring to a mixture of diterpenoid alkaloids from the yew tree (genus: Taxus). Taxine is responsible for the toxic properties of the yew tree that has been documented in historical and fictional literature, from Julius Caesar to Shakespeare, and from Agatha Christie to T.S. Eliot. The chapter treats the history, isolation techniques, structure elucidation, chemistry, and pharmacology of Taxine.

Chapter 3 by Mary D. Menachery surveys the alkaloids of South American Menispermaceae (moonseed family). Many different structural types are included in this family. The alkaloid-bearing plants are woody-vines, shrubs, or small trees. Several of these species possess potent curare activity. The chemistry as well as pharmacology of these alkaloids is summarized.

Chapter 4 by Russell J. Molyneux, Robert J. Nash, and Naoki Asano treats the chemistry and biological activity of the calystegines and related nortropane alkaloids. These polyhydroxylated bicyclic alkaloids represent another class of compounds that inhibit glycosidases, producing profound effects in biological systems by disrupting the essential cellular function of glycoprotein processing.

Chapter 5, a related chapter by Robert J. Nash, Naoki Asano, and Alison A. Watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. Topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.

Editorial Reviews

Review

Geoffrey A. Cordell
This is the eleventh in the series of volumes intitiated in 1983 to complement The Alkaloids: Chemistry and Pharmacology series of Academic Press. This particular volume brings together five chapters, one major contribution from Paul Schiff and four shorter contributions from a distinguished group of authors, which collectively maintain the quality of the series. Schiffs' marvellous tour-de-force demonstrates his preeminent knowledge of the alkaloids of Thalictrum species, and it is both refreshing and inspiring to see the wealth of data on these diverse alkaloid groups presented in such a lucid and well-organised manner....Overall this volume is strongly recommended for university and corporate libraries...
